Automatic porting of C++ to javascript - 1 views

    asm.js: it's really fast, backwards compatible, and now in the release version of Firefox. "By doing this the result is highly optimized and can be converted directly from this Asm.js syntax directly into ASSEMBLY without having to interpret it, as one would normally have to do with JavaScript" Here is great introduction to asm.js and C++ to js compilation: http://ejohn.org/blog/asmjs-javascript-compile-target

    No, actually I only know him from several documentaries. von Neumann probes, those I know quite well from sci-fi :). Alastair Reynolds' Revelation Space is a good example btw. Here's a relevant link: http://en.wikipedia.org/wiki/Self-replicating_machine#NIAC_studies_on_self-replicating_systems

    why are we not getting these type of startups in Europe .... btw: Will is british
  • ...1 more comment...
  •  
    Nobody in Europe would invest 13Mio $ (or the equivalent in €) venture capital for this idea, it's just a different mentality. In Europe, VCs start to get interested when the investment risk is significantly lower.
  •  
    I agree, the mentality is different, it's hard to find VC funding for hardware stuff, even more so if you wanna shoot your HW into space. but there is movement, e.g. pioneers.io, they are in vienna and are actively trying to get more VC funding (in europe) for HW and other engineering startups
  •  
    thanks for the link ... just read this blog ... http://pioneers.io/blog/space-race-2-0-putting-satellites-into-the-hands-of-everyone a lot of selling talk but fundamentally I agree that they have a point ... and as ACT we will face the criticism in not so long that we have not managed (nor tried hard enough) to convince ESA about the need to embrace this "new space"

Do the math #dothemath - 4 views

    My daily read, a collection of blog posts related mostly to energy by UCSD prof Tom Murphy. Especially his experiments into home energy storage and his "do the math" attitude towards renewables are insightful and if not, then sometimes just plain funny.

    on a somewhat related note. court document from the fbi agent that was chasing that silk road guy a friend sent me the other week. an interesting read if only because i found the content quite unexpected e.g. 2 pages of login instructions http://www1.icsi.berkeley.edu/~nweaver/UlbrichtCriminalComplaint.pdf

Picture This: NVIDIA GPUs Sort Through Tens of Millions of Flickr Photos - 2 views

  •  
    Strange and exotic cityscapes. Desolate wilderness areas. Dogs that look like wookies. Flickr, one of the world's largest photo sharing services, sees it all. And, now, Flickr's image recognition technology can categorize more than 11 billion photos like these. And it does it automatically. It's called "Magic View." Magical deep learning! Buzzword attack!

    and here comes my standard question: how can we use this for space? fast detection of natural disasters onboard?
  •  
    Even on ground. You could for example teach it what nuclear reactors or missiles or other weapons you don't want look like on satellite pictures and automatically scan the world for them (basically replacing intelligence analysts).
  •  
    In fact, I think this could make a nice ACT project: counting seals from satellite imagery is an actual (and quite recent) thing: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0092613 In this publication they did it manually from a GeoEye 1 b/w image, which sounds quite tedious. Maybe one can train one of those image recognition algorithms to do it automatically. Or maybe it's a bit easier to count larger things, like elephants (also a thing).

    In HiPEAC (High Performance, embedded architecture and computation) conference I attended in the beginning of this year there was a big trend of CUDA GPU vs FPGA for hardware accelerated image processing. Most of it orbitting around discussing who was faster and cheaper with people from NVIDIA in one side and people from Xilinx and Intel in the other. I remember of talking with an IBM scientist working on hardware accelerated data processing working together with the Radio telescope institute in Netherlands about the solution where they working on (GPU CUDA). I gathered that NVIDIA GPU suits best in applications that somehow do not rely in hardware, having the advantage of being programmed in a 'easy' way accessible to a scientist. FPGA's are highly reliable components with the advantage of being available in radhard versions, but requiring specific knowledge of physical circuit design and tailored 'harsh' programming languages. I don't know what is the level of rad hardness in NVIDIA's GPUs... Therefore FPGAs are indeed the standard choice for image processing in space missions (a talk with the microelectronics department guys could expand on this), whereas GPUs are currently used in some ground based (radio astronomy or other types of telescopes). I think that on for a specific purpose as the one you mentioned, this FPGA vs GPU should be assessed first before going further.
  •  
    You're forgetting power usage. GPUs need 1000 hamster wheels worth of power while FPGAs can run on a potato. Since space applications are highly power limited, putting any kind of GPU monster in orbit or on a rover is failed idea from the start. Also in FPGAs if a gate burns out from radiation you can just reprogram around it. Looking for seals offline in high res images is indeed definitely a GPU task.... for now.
  •  
    The discussion of how to make FPGA hardware acceleration solutions easier to use for the 'layman' is starting btw http://reconfigurablecomputing4themasses.net/.

The 70 Online Databases that Define Our Planet - 0 views

  • an ambitious European plan to simulate the entire planet. The idea is to exploit the huge amounts of data generated by financial markets, health records, social media and climate monitoring to model the planet's climate, societies and economy. The vision is that a system like this can help to understand and predict crises before they occur so that governments can take appropriate measures in advance.
